<p>PURPOSE:To obtain a stabilizer with a small initial noise value and a small temperature rise value by filling up the case accommodating the impedance element with a resin composite for a pouring mold excellent in low shrinkage, adherence, insulation, sound absorption, thermodeterioration resisting. CONSTITUTION:Vinyl monomer as a crosslinking agent, inorganic filler and catalyst are added to the denatured unsaturated polyester resin composed of 10-95wt% of aromatic hydrocarbon resin denatured unsaturated polyester resin and 95-5wt% of cyclopentadiene system resin having a softening point 50-160 deg.C. In this constitution, aromatic hydrocarbon resin denatured unsaturated polyester resin is the resin wherein aromatic hydrocarbon resin is added to the unsaturated polyester and reacted by heating, while cyclopentadiene system resin is composed of 80-65wt% of cyclopentadiene system monomer and 20-35wt% of ester combination containing monomer.</p> |
